As a psychologist, I don't provide medical advice, but I can tell you the general guideline is yes, you should stay hydrated by drinking water following any surgical procedure. However, you'll want to avoid using a straw as it can possibly dislodge the blood clot that forms to assist healing. It's also advised to take small sips, rather than swigs. But remember, you should definitely consult with your dentist or oral surgeon for more specific medical advice.
